4. What are viruses? Viruses are too small to be seen by the naked eye.
No cells; not living
Viruses are parasites. They can't multiply on their own, so they have to invade a 'host' cell and take over its machinery in order to be able to make more virus particles.

5. Spread of Viral & Bacterial Diseases
Viral and bacterial infections are both spread in basically the same ways.
A person with a cold can spread the infection by coughing and/or sneezing.
Bacteria or viruses can be passed on by touching or shaking hands with another person.
Touching food with dirty hands will also allow viruses or bacteria from the intestine to spread.

7. How to avoid infection
Wash your hands thoroughly (often one of the best ways to avoid catching a cold).
Shaking hands with someone who has a cold is risky, so avoid rubbing your eyes or nose afterwards.
Food should be cooked or cooled down as quickly as possible.
Vegetables and meat must be stored separately and prepared on separate chopping boards.
Meat should preferably be served well-done.
Remember that food with these invisible organisms does not necessarily smell bad.
Some organisms are killed as the food is cooked, but they can still leave toxic substances that may cause diarrhoea and vomiting.

8. Treatment of Viral Infection
Viruses can't multiply until they are inside the body's cells.
This is the reason why the treatment of virus infections is usually left up to the patient's own immune system, although it may be hard to accept when the doctor says the only cure is for 'nature to take its course'.
Drinking plenty of water is good
Staying at home. People who go to work or school in this condition not only risk spreading the virus to their colleagues but also run a higher risk of catching a bacterial infection
